Some cosmic rays come from the sun, some from elsewhere in our Milky Way, and others, called extragalactic cosmic rays, trace ...

Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

A new experiment with momentum-entangled helium atoms could help unite quantum mechanics and general relativity.

The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on ...

Physicists have achieved a long-sought goal in demonstrating quantum entanglement using the momentum of atoms, rather than ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

Physicists at the world’s largest atom collider have observed three new exotic particles as they continue to search for clues about the mysterious forces that bind subatomic particles together, they ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

In CERN’s high-temperature superconducting laboratory near Geneva, a wiring machine combines dozens of strands of niobium–tin ...
